Who profits from the European integration: My point of view

In my opinion the advantages of the increased European integration experienced in the last couple of years are distributed in a unfair way.
Big (core-) European corporates enter new markets with weak local competition due to lower efficiency. They destroy the local competition, causing increased unemployment given that its holds true that lower efficiency equals more workforce employed.
People there can now maybe shop at lower prices, too bad if they don't have the money because they have no job anymore.
Corporates further profit by reduced expenses (cheaper labor, less regulation and taxes) even if they do not shift f.e. production sides (reduce tax by profit shifting via licenses to European tax havens, race to the bottom in corporate taxes, etc.).
I made a little drawing on a p/l of one of those corporates:

So now that its seems clear (at least in my view) who wins, who is the one that looses?
The average worker that has nothing more than work to sell, no land, no capital, no nothing.
Mainly unskilled workers, yet also highly skilled white collar workers suffer. The payment they can demand from companies as compensation for their work will reduced due to increased supply.
